BENTON Vitamin C Serum 20% Pure Vitamin C (1.01 fl. oz.) — Anhydrous, Airless Pump for Brighter, Smoother Skin

BENTON Vitamin C Serum is a high-concentration, anhydrous 20% pure vitamin C serum in an airless pump designed to support brighter, smoother-looking skin while minimizing oxidation.

This formula uses pharmaceutical-grade British vitamin C in its natural white form and keeps it stable by removing water and housing it in an airless container. The result is a concentrated, cream-like serum that delays yellowing from oxidation, delivers antioxidant ingredients alongside hydration actives, and is designed for everyday cosmetic use to help improve skin tone and texture.

How does a 20% anhydrous vitamin C differ from typical serums?

Most vitamin C serums are water-based and can oxidize quickly, turning yellow and losing potency. BENTON’s anhydrous (no-water) approach reduces that oxidation risk and maintains the raw vitamin C’s white color; the airless pump further limits air exposure, extending useful life after opening.

• 20% pure vitamin C raw material sourced from Britain for potency.
• Anhydrous formulation eliminates water and alcohol to slow oxidation.
• Airless container reduces oxygen contact and product degradation.
• White appearance indicates stabilized, unoxidized vitamin C.

Will this serum be harsh on sensitive or reactive skin?

BENTON developed this formulation with three years of research to balance stabilization and skin tolerance. The serum is described as cream-like with over 70% moisturizing agents and includes soothing ingredients like adenosine and ectoin to improve absorption while being gentle on sensitive skin types.

• Patented stabilization method designed to reduce irritation risk.
• High moisture content softens texture and aids skin barrier support.
• Added actives—glutathione, vitamin E, tocotrienol, ferulic acid—complement vitamin C without aggressive solvents.
• Recommended layering with hydrating toner or gel to further reduce sensation.

What results can I expect and how should I apply it for best effect?

The serum targets evenness of tone, surface texture, and visible vitality rather than making medical claims. Because it’s concentrated, a small amount goes a long way—about 0.2 g per application—and pairing it with hydrating steps increases comfort and absorption.

• Use on a cleansed, slightly moisturized face to optimize uptake.
• Dispense a pea-sized amount (approx. 0.2 g) and spread gently across the face.
• If you feel warmth, soothe with a calming gel or apply a hydrating mask afterward.
• Store upright in a cool place and use within approximately six months after opening for best quality.

How long will the product stay effective after opening and why?

Because water and alcohol are absent and the container is airless, oxidation is delayed compared with conventional serums. BENTON estimates effective performance for roughly six months after first use, though storage conditions and exposure to heat or light can influence longevity.

• Anhydrous base reduces moisture-driven degradation pathways.
• Airless pump limits oxygen exposure at every dispense.
• Keep away from direct sunlight and high temperatures to preserve potency.
• Check color and scent—deep yellowing or off-odor indicates oxidation.

Who is this for: BENTON Vitamin C Serum is aimed at people who want a high-strength vitamin C cosmetic with a stabilized format—ideal for those concerned about oxidation in brightening serums, users with sensitive skin who prefer cream-like textures, and anyone seeking to improve skin tone and surface texture without water-based solvents. It fits into morning or evening routines when paired with hydrating preparations and sunscreen in daytime use.
